This is one of the simplest and most obvious examples, after this week’s announcements: Google is now offering not one, but two mobile operating systems. While they undoubtedly share code, I can’t help but think back to ten years ago, when Microsoft was vehemently protesting about how much code was shared between the Windows NT/Windows 2000 operating systems and the Windows 95/98/ME operating systems. If I make a screen two inches smaller, should I use Android instead of Chrome OS? If the keyboard works with my fingers instead of my thumbs, I should use Chrome OS and not Android? I know Google is convinced its employees are smarter than everyone else in the world, but this is a product management problem, not a computer science problem.

It makes no sense to me why Chrome OS isn’t based on Android. Maybe there’s a good answer to this, but Google hasn’t given it.
